Its distinguishing feature is a flecked bezel and band molded from recycled resin scraps recovered at Casio manufacturing facilities. Casio announced the model in May 2024, with a Japan release planned for June 8 that year. This is a model overview based on Casio’s published information, not a firsthand wear or performance review.
What is the G-Shock G-5600SRF-1?
Casio introduced the G-5600SRF as its eighth G-Shock collaboration with the Surfrider Foundation. The exact product designation used on Casio product pages is G-5600SRF-1. It pairs the familiar square 5600 digital-watch format with a distinctive speckled exterior and Tough Solar charging. Casio’s May 15, 2024 announcement described it as a shock-resistant watch with a bezel and band made using recycled resin scraps recovered from Casio manufacturing facilities: Casio’s announcement.

What is the G-5600SRF-1 made from?
Casio says resin scraps from its manufacturing processes are shredded, mixed into urethane, and molded into the bezel and band. The material mix produces a flecked pattern, so the appearance varies from one watch to another. This supports describing the exterior as containing recycled manufacturing scrap; it does not establish a quantified lifecycle or ocean-plastic benefit.
The collaboration is with the Surfrider Foundation, a nonprofit focused on protecting oceans, waves, and beaches. Casio’s 2024 announcement reported that the foundation had about 250,000 supporters active in 23 countries; that is Casio’s dated figure, not a current count independently verified here.
#1 Best Overall
Is the G-5600SRF-1 solar powered?
Yes. It uses Casio Tough Solar, which charges the watch through light. Casio estimates approximately 12 months of operation on a full charge without further solar charging while functions are in use, or approximately 22 months with power saving enabled. These are manufacturer operating estimates, not independent runtime test results.

That measurement alone does not confirm that a particular replacement band will fit; check the exact part with Casio or an authorized parts source before buying.

What does it cost, and is it available?
Casio India lists an MRP of ₹9,995 including tax on its regional page: Casio India’s G-5600SRF-1 listing. This is a region-specific listed price, not a universal current price, and it may change. Current stock and availability have not been verified, so confirm the model designation and seller’s inventory before purchasing.
Who is the G-5600SRF-1 for?
Its practical appeal is the combination of a compact, lightweight 5600-series form, solar charging, and standard digital timing functions with a visually distinctive recycled-resin exterior. Buyers choosing among G-Shock models should compare exact case dimensions and fit, charging system, timekeeping functions, water resistance, and display readability. The available specifications do not establish a controlled comparison with another model, so those trade-offs depend on the candidate watches’ own published details and the wearer’s preferences.
